1 claim. (ci. 24o-12s) This invention relates toa lamp, and moreparticularly to a lamp which includes a novel means for turning the llight bulb on or of. l

d The object of the invention is to provide a lamp which includes amovable stem, whereby when a person desires {to actuate the light bulbor turn the light bulb on or off, it is only necessary to manually gripa portion` of the stem and move the stem downwardly so as to cause aswitch to be engaged or actuated.

A still further object of the invention is to provide a lamp which isconstructed so that a light bulb may be turned on or oii without thenecessity of manually pulling a chain, or turning a switch, wherein thepresent invention facilitates the actuation of a lamp as for examplewhen the lamp is located in a darkroom or other locality, since thepresent invention permits the lamp to be more readily actuated.

A further object of the invention is to provide a lamp which isextremelysimple and inexpensive to manufacture.

Other objects and advantages will be apparent vin the course of thefollowing description.

In the accompanying drawing, forming a part of this application, and inwhich like numerals are used to indicate like parts throughout the same:

Figure 1 is an elevational view illustrating the lamp of the presentinvention.

Figure 2 is an enlarged sectional view taken on line 2-2 of Figure l.

Figure 3 is a sectional view taken on line 3-3 of Figure 2.

Referring in detail to the drawing, the numeral indicates the lamp ofthe present invention, and the lamp 10 includes a base which isindicated generally by the numeral 11. The base 11 is provided with anouter section 12 so that the base 11 has a suitable formation. The base11 is provided with a recess 13 in its lower portion, and the basell isalso provided with a vertically disposed bore 14 which communicates withthe recess 13. The numeral 1S indicates a horizontally disposed platewhich is 'positioned inthe recess 13, and the plate 15 may be secured inplace by means of suitable securing elements 1 6. The numeral 17indicates wires which extend through a central aperture 18 in the plate15.

The numeral 19 indicates a switch which is connected to the plate 15,and the switch 19 is provided with a push button 20 for a purpose to belater described. v

There is further provided a vertically disposed sleeve or guide 21 whichis seated in the bore 14, and the sleeve 21 is provided with a cutout22, in the lower portion thereof,

and this cutout 22 denes a stop shoulder 230 in the lower portion of thesleeve 21. The numeral 24 indicates a` lamp shade which is connected tothe stem 23 in any suitable manner.

The stem 23 is provided with a longitudinally extending passageway 25which includes an upper section 26 of a reduced diameter, and a lowersection 27 of increased diameter. The numeral 28 indicates a cutoffspring which has its upper portion fitted inthe section 27, and thelower will not become disconnected from the sleeve 21, as forlee,bracket 33 further includes a horizontally disposed lower iinger32which is movably mounted in the cutoli 22. The finger 32 is mounted tomove into and-out of engagement with the push button 20, and the finger32 is also mounted to, move into and out of engagement with the stopshoulder 230 of the sleeve 21.

From the foregoing, it is apparent that there has been provided a lampthat includes a manual means for actuat- Aing the light bulb of thelamp. According to the present invention, with the parts arranged asshown in the drawing, it will be seen that by gripping the stem 23 andmoving the stem 23 downwardly, the bracket 33 will be moved downwardlyand the bracket 33 is connected to the stem 32 as at 31. As the bracket33 moves downwardly, the linger 32 will move down into engagement withthe push button 20 so as to actuate the switch 19. Since the switch 19is connected to the light bulbthrough the wires 17, it will be seen thatthe light bulb can be turned on or oli by the downward movement of thestem 23; When pressure is released on the stem 23 the, cutoff spring 28will return the stem Z3 to a raised position. Then, when the userdesires to again actuate the light bulb or turn the light bulb on oroli, it is only necessary to repeat the cycle and again move the stem 23downwardly. It is to be noted that when pressure is released on the stem23, upward travel of the stem 23 will be limited by the finger 32 whichmoves in the cutoii 22, since the finger 32 will engage the shoulder 230on the lower portion of the sleeve 21, and this inter-engagement betweenthe linger 32 and the shoulder 230 provides a stop means for limitingupward travel of the stem 23.

While the present invention has been described in connection with theturning on or off of a light, it is to be understood that the switch 19may be of a type which selectively controls actuation of one or morefilaments or bulbs so that such lights can be turned on or oli otherwiseactuated by the downward movement of the stem 23.

The parts can be made of anysuitable material and in .different shapesand sizes.

The sleeve 21 is secured to the base in any'suitable manner, as forexample by means of securing elements, or by means of an adhesive or thelike. The lamp of the present invention consists of a minimum number ofparts and is simple and inexpensive to make whereby the lamp can beproduced and sold at a very minimum cost. Also, the construction of thelamp permits the lamp to be readily and conveniently assembled ordisassembled.

The lamp is constructed so that a light can be turned on or oii by themanual downward pressure on .the stem 23. Furthermore, this mechanismcan be used for changing from one bulb being on or oil to two or morebulbs being on or oli.

The brackets 33 also serves to insure that the stem 23 stem 23 and thisis due to the fact that the nger 32 will engage the stop shoulder 230.

,l It is to be noted that the lamp of the present invention isconstructed so that a person does not have to hunt for a button to pushor a knob to turnror a chain to pull and to actuate the lamp it is onlynecessary to push down on the stem and any portion of the stem may begripped to push down.' Similarly when a person wishes to put out thelight the same downward pressure will turn oi the light orchange fromone bulb being on to others being on by the proper wiring appliedthereto. All of the working parts are strong and are safely enclosed asshown Vinv the drawing. Y y

The base can have any suitable or desired formation since it may besquare or of any other design or shape.

The above description of the invention is for illustrative purposes onlyand it is understood that modifications may be made in the constructionWithin the scope and spirit of Vthe following claim.

I claim: A lamp of the class described, having a base, a recess in thelower portion of said base, said base having in itsr l said plate, wiresextended through said aperture and connected to said switch, a sleeveseated in said bore and having a lower end abutting said plate, therebeing a cutout in the lower portion of said sleeve providing a stopshoulder, a movable stem seated in said sleeve, there being alongitudinally extended passageway in said stem for the passagetherethrough of said wires, said passageway including an upper sectionof reduced diameter and a lower section of increased diameter, and acoil spring having its upper end projecting into the lower section ofthe passageway, said coil spring having the lower end abutting saidplate, a bracket including a vertically disposed leg positioned in saidcutaway portion and secured to said stem, said bracket further includinga horizontally disposed ingery which is provided to` move into and outof engagement with said switch, said nger being mounted to move in saidcutout and being mounted to move into and out of engagement with saidshoulder.
